Question

6-2

Answer 1

Answer:

  Team 3 Turtle, by 4 minutes

Step-by-step explanation:

The speeds of each of the turtles can be computed from ...

  speed = distance/time

Then for each of the turtles, the training pace is ...

  Team 1 Turtle: (18 ft)/(6 min) = 3 ft/min

  Team 2 Turtle: (12 ft)/(4 min) = 3 ft/min

  Team 3 Turtle: (10 ft)/(2 min) = 5 ft/min

The times required to cover the 30 ft distance at these paces are ...

  time = distance/speed

  3 ft/min ⇒ (30 ft)/(3 ft/min) = 10 min

  5 ft/min ⇒ (30 ft)/(5 ft/min) = 6 min

The 2nd-place finishers will take 10-6=4 minutes longer.

The expected winner is Team 3 Turtle by 4 minutes.
